Aliphatic aldehydes and allethrin in mosquito-coil smoke.
Presence of aliphatic aldehydes and allethrin in the smoke produced by two brands of mosquito-coil was determined by high performance liquid chromatography. It was observed that burning mosquito-coil produces a greater amount of formaldehyde, acetaldehyde and acrolein in the gaseous phase, whereas lesser amount of particulate-bounded aldehydes. Aldehydes bounded in particulates were, however, enriched in terms of concentration. Allethrin was found to occur only in particulates of 0.1-1.0 micron size. The results reveal that allethrin may not be capable of attacking the mosquitoes effectively.
